Mandevilla

I was at the Home Despot and picked up a Sun Parasol Mandevilla. It
was big and $10.
Since I'm in Atlanta, 7b, and freezing temps are not uncommon, I'm
going to either bring it in or enjoy it for the season.
How far can you cut these back, and how much light will it need to
overwinter?
I suppose I need to build a trellis now. I wonder if I've just given
myself a problem I don't need!
Somehow, I got rid of all my honeysuckle, I didn't think that was
possible!

My wife bought four nice sized ones at $15 per. Nursery lady said they may
be marginal in our area, but my wife assured her that she was wrong. We'll
see. They are a nice looking plant, very healthy and established, and
should do well on the fence. I just hope they make the winter. We have
some cold spells here. Must get them planted soon so they have a good shot
at making it through the winter.

Along that line, I live in Toquerville, Utah. SW Utah, 27 miles north of
Arizona line, about the same distance in east of Nevada line. In different
gardening books, I am classified as different zones. I am still not sure
what zone I am actually in.
I see containers that say good for zone such and such. Unless you're smack
in the middle, the outcome could be a tossup.
I brought some birds of paradise back to Las Vegas from San Diego, those
ones that grow all over down there. I did not expect them to last past the
first summer. They are five years old now, and although not thriving like
the ones along the California coast, they are alive and well.
I pretty much go by what the people at the nursery say. A local nursery
near my little home town. I just take in what the one twenty miles away
says about what will grow where. Just like the labels. And a lot of the
staff at those nurseries are told to say anything will grow anywhere, just
load it on their truck.
You can position things so they are protected either from wind or sun or
cold, and they may perform good. Things might not be supposed to grow here
and there, but they do. Then things that should grow don't. I went through
eight ocotillos in Vegas under a nursery guarantee, the third and fourth
planting being done by their staff, and none of them lived. There was a
huge one in the same planter that we started with one cane we stuck in the
ground with no soil and no fertilizer, and now it is a monster.
Go figger.

There are several species of Mandevilla, some are tender and one is
hardy
M. boliviensis, M. splendens (aka Dipladenia), many hybrid
Mandevillas such as
Alice du Pont are quite tender and will not survive frost.
M. laxa, common name Chilean Jasmine is root hardy to about 5 F.
This comes from Sunset Western Garden Book.
I didn't see any info about 'Sun Parasol' but see if your tag says
(M. laxa)
it should be OK.

I got the tag, and mine just says Sunparasol "Pretty Crimson Mandevilla."
There is no hardiness or temperature rating. I did find on google it is
good for zone 8-10. A lookup of my zipcode states I am in zone 8, although
I have seen it rated differently. I'll plant it, and see what happens. It
should have enough time to get established before winter.
